The GReddy FV blowoff valve is a new generation of blowoff valve. The unique "Floating Valve" design incorporates a revised adjustable dual spring system while retaining the advantages of the previous models' push valve structure and silicone diaphragm control.

The improved design makes the spring preload adjustment less dependent on idle, while providing increased response, valve travel, flow, and resistance to premature valve lift under any conditions.

The GReddy FV adopts the same size and mounting and outlet position as the previous GReddy RS and RZ models, allowing for retrofitting to existing applications.
